Description

Flexible automatic carton waste removing device

Technical Field

The invention belongs to the field of woodworking machinery, and particularly relates to a flexible automatic carton waste removing device.

Background

In the carpenter industry, the board furniture trade, the panel of various specifications need pack after accomplishing the processing, and the material of packing generally is the corrugated paper, and the transportation is convenient for after the panel packing to can effectively prevent the damage of panel in the transportation.

The packaging process of the plate comprises the following steps:

firstly, a paper cutter prepares a cut paper box unfolding material (called a paper board below) and outputs the paper box unfolding material to a designated position by a system belt conveyor, and the paper box unfolding material is shown in figure 12.

And secondly, removing waste materials at the edge of the paper board (at the moment, partial paper fiber connection is still existed between the waste materials and the main materials), wherein the waste materials are shown in a figure 13.

And thirdly, placing the stacked plates or single plates (such as door plates) on the paperboard from which the waste materials are removed.

And fourthly, folding the packaging paperboard into a paper box.

And fifthly, sealing and packaging.

The invention is mainly aimed at the second process in the plate packaging process, namely the unfolded paper board edge waste removing process.

At present, in the domestic wood processing industry or the panel furniture industry, the removal operation of the cardboard waste before the packaging of the panels is basically completed manually.

Manual removal of waste presents several problems:

firstly, the tearing waste material speed of an operator is low, so that the efficiency of the whole packaging line is mainly determined by the operator; secondly, the worker temporarily leaves the post to stop the packaging work, so that the production efficiency of an enterprise is directly influenced;

secondly, because the waste material and the unfolded paper box are connected by paper fibers, the randomness of manually tearing the waste material is high, errors are easy to occur, and if the errors happen, the waste material is torn while the paper board is torn, so that the paper box is damaged, and the quality problem of packaging is directly caused;

third, if the carton unwind is large (such as in door panel packaging), the carton unwind size may be 2.1 meters by 2.5 meters. The cardboard needs to be turned or rotated many times to remove the waste around, which not only wastes time, but also causes excessive creases in the cardboard during turning or rotating, thereby deteriorating the quality of the package.

The technological process of equipment operation is as follows:

before the equipment starts to work, all mechanisms are in initial state positions:

the initial states of the first side waste removing device 2 and each mechanism on the trolley are as follows:

1) the first side scrap removing device 2 is located away from the pressing beam 3

2) The two mobile clamps 16 are in a position close to the fixed clamp 15

3) The fixed clamp suction cup 15 and the moving clamp suction cup 16 of the first side slug removal device 2 are both in the raised position

4) All finger cylinders 22 on the pliers are located away from the suction cups 20

The second side waste removing device 4 and the upper mechanism thereof are in the following initial states:

1) the movable frame 45 is located away from the pressing beam 3

2) The gripper jaws 44 of the gripper are in an open state

Thirdly, the initial state of the press beam 3 is that the press beam cylinder 43 is at the lifting position.

The working sequence of each mechanism of the equipment is as follows:

the system belt conveyor is positioned between two large-span supporting legs of the waste removing device, materials are conveyed to a designated position below the waste removing device through the belt conveyor, and the conveying direction of the materials is the length direction (+ X direction) of the paper board.

Secondly, after the materials are in place, the pressing beam cylinder 43 presses down to stabilize the materials and the paper boards

Thirdly, the direction of the waste material on the cardboard is shown in fig. 11

Process for removing waste material

1) Removing waste I: and the 47 clamp moving mechanism pushes the 45 moving support and the 44 clamp to move to a certain position along the-Y direction and then stop, all the 44 clamps are closed at the same time to clamp the waste I, and the 47 clamp moving mechanism drives the whole clamp to move backwards (+ Y direction) so as to tear off the waste I. When the waste I is pulled back to a certain position, the 44 clamps will open, and the mechanism will continue to move back until the 12 blanking bars located on the frame strip the waste I out of the machine onto the ground or onto a waste conveyor belt on the ground.

2) Removing waste material II: waste material II need through the 15 fixed sucking disc tongs that are located 2 first side waste material remove device and 16 remove the sucking disc tongs and snatch the back, rethread 2 first side waste material remove device along-Y direction removal to tear.

The specific process is as follows: after the materials are in place, the 17 trolley traveling driving mechanisms on the 2 first side waste removing devices move the trolley to the designated position according to the width of the paper boards, and the traveling distances of the trolley in the + Y direction are different according to different widths of the paper boards. After the trolley is in place, the 15 fixed suckers are just positioned at the head of the waste material II. At the same time, the two 16 mobile suction cups on the 2 first side waste removal device will also be adjusted in position according to the length of the cardboard. The mechanism for driving the 16 moving suckers to move is an 18 moving sucker driving mechanism, and the mechanism is provided with two sets of large and small synchronous belt driving devices, wherein the speed ratio of the two sets of devices is 1: 2, when one 16 moving suction cup moves to the tail end of the paper board, the other 16 moving suction cup is just positioned right in the middle of the tail end 16 moving washing plate and the tail end 15 fixed suction cup, so that the stress of tearing the waste material II is ensured to be uniform.

After the positions of the trolley and the suckers are adjusted in place, the 20 suckers are pressed down through the 21 sucker moving device, and after the 20 suckers suck the waste material II, the 21 sucker moving device is lifted, and the waste material II is lifted. Then the 22-finger air cylinder in the open state moves along the + Y direction under the pushing of the 23-finger air cylinder moving mechanism, and the 22-finger air cylinder clamps the waste material after the waste material is in place. After the above actions are completed, the waste material II is tightly grabbed, and at this time 2, the first side waste material removing device moves backwards (-Y direction), and the waste material II is peeled off the paperboard. When the trolley moves to a certain position, the 22 finger air cylinder is opened, the 20 suction cups blow air, and the waste II generally falls off. If some special paper boards are encountered, the waste materials can be stuck on the fingers of the 22-finger cylinder, so in order to ensure that the waste materials II fall off, the mechanism needs to complete the following actions, namely, the opened 22-finger cylinder moves backwards (-Y direction), the waste materials II can touch the 24 blanking rods, and the blanking rods can strip the waste materials II out of the machine.

And fourthly, after the paper board is stripped from the waste, the pressing beam air cylinder 43 is lifted, and the system belt conveyor conveys the material and the paper board to the next working procedure.

And fifthly, after the previous material is conveyed out, the next material is conveyed to the position below the waste removing device, and the first side waste removing device 2 and the second side waste removing device 4 also finish the residual action at the moment, namely, the initial state is about to be entered. After the next material is in place, the first side scrap removal device 2 and the second side scrap removal device 4 have also entered the initial state, at which point the next cycle begins.

Although the present invention has been described in detail with respect to the above embodiments, it will be understood by those skilled in the art that modifications or improvements based on the disclosure of the present invention may be made without departing from the spirit and scope of the invention, and these modifications and improvements are within the spirit and scope of the invention.
